DRYING BLOWER FOR- ENVLELQPE-EEAKING lMAQHINES.

Specification of Letters Patent.

Application filed February 24, 1920. Serial No. 360,967.

T 0 all who-m it may concern:

Be it known that l. AnoisoN E. Acous- TINE, residing at Hackensack. in.the county of Bergen and State oi. New Jersey, have invented certain newandv useful lIHPl'OVC- ments in Drying Blowers "for Envelope- MakingMachines, of which the following is a specification.

This invention relates to drying blower for envelope-making machines.

' An object 01" the invention isto provide a simple and eflicient meansfor drying the freshly gummed portions of the envelopes A further objectis to provide a, drier device employing a fan and being of a char actersuch that the air blast from the fan will be directed against theenvelopes in an efiicient manner.

A further object is to provide a drying blower which may be constructedas a part of the envelope-making machine and which may, if desired, bedriven by a moving part of the machine.

A further object is to construct the drying blower so that it includesan air box which is, formed separately from the fan element and which iscapable of being read-.

ily removed from the fan element and from the remainder of the machinewhenever desired. 1

Other objects and aims of theinvention, more or less specific than thosereferred to above will be in part obvious and in part pointed out in thecourse of the following description of the elements. combinations,arrangements of parts and applications of: principles constituting theinvention, and. the scope of protection contemplated will be indicatedin the appended claims.

In the accompanying drawings which are to be taken as a part of thisspecification, and in which I have shown merely a preferred form ofembodiment of, the invention:-

Figure 1 is a diagrammatic view illustrating in side elevation a portionof an envelope-makingmachine, a drying blower constructed in accordancewith'this invention. being illustrated in operative associationtherewith.

Figure 2 is a side elevational view, partly in section, of the air boxappearing in Fi 1, and

Figure 3-.is a top plan View of the structure seen in Fig. 2.

In onvelopoanairing machines usually an endless chain is provided havingtins thereon forming a plurality of stalls L into which is ted the newlygumined envelopes 1. The

chain, moves about spaced rollers '2 and 3 on a. suitable frame member4l-. the envelopes being fed into the stalls L at the upper end otthechain. as at the point 5, and travelling with the chain in the directionof the arrows. "he envelopes finally leave the chain at the point 6 andfall into suitable receiving means. The travel of the chain is slow sothat the period of time during which the envelopes remain in thestallsli is intended to be sufiicient to allow the new gumillustratedand. forms the basis otthis invention. it consists in arotary air fan (ito which is connected an air box l l. The :t'an may beoi any type but is preferably of thetype substantially as indicated,having discharge nozzle portion "2' throuo'h which the air is deliveredinto the box ll. The box H is provided with a collar portion'8 adaptedto detachably but tightly engage over the nozzle portion 7 or the fan sothat all of the air from. the fan is delivered into the interior of thebox. The construction and arrangement of the parts of the bo'xis clearlyseen in Figs 2 and '3 of thedraivingrs. wherein it will be noted thatthe upper wall, 9. is inclined sul'stantially to conform to the path ofmovement of the envelopes. This wall is formed with a multitude otperforations, as 10, therethrough 'through which the air from the fanisdirected upwardly against the passing enelopes.

The box is preferably largest at its end nearest the fan and tapersgradually to ar-100 smaller size at its end furthest from the fan. Thepurpose of this arrangementis to produce a more uniform discharge of airfrom all of the apertures 10. The direct blast of air from the fan willnaturally be 105 in direction toward the reduced end of the box. Thereduction in size and the consequent less number of apertures 10 at thefar end of the box will cause the air to bank,

or pile up, until the pressure is substantially 11o eerie. M

uniform throughout the interior of the box. The air blast from each ofthe apertures 10 will be substantially uniform, and the position of thewall 9 insures that the blasts from all of said apertures 10 will bedirected upon the passing envelopes.

A maximum degree of efliciency is thus attained so that it will bepossible to use a comparatively small fan to provide all of the airrequired.

The fan may be driven in any suitable manner, either by a moving part ofthe envelope-machine mechanism, or by an inde pendent motor. As anexample, it is herein illustrated to be driven by a wheel 11 forming apart of the envelope-machine mecha nism, a belt 12 extending from thewheel. 11 to the fan pulley 13.

The blower device may be supported in any appropriate manner but ispreferably supported by the frame of the envelope-machine so that it canbe moved as an entity therewith. For this purpose the drawing shows the"fan to be provided with suitable ears 14 which are attached by bolts orscrews, to the frame work of the machine.

The engagement of the collar 8 over the nozzle 7 will hold the air box Hin position upon the fan and will permit convenient removal of the airbox whenever occasionv may require.

As many changes could be made in this construction without departingfrom y the scope of the invention as defined in the following claims,.itis intended that all matter contained in the above description or shownin the accompanying drawings, shall be in terpreted as illustrative onlyand not in a limiting sense.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In an envelope-making machine having acarrier for the newly gummed envelopes, the combination therewith of adrying blower having parts by which to direct a blast of air against theenvelopes carried by said carrier, drive connectionsbetween the machineand said drying blower, and.

means by which said drying blower is connected with said machine to becarried thereb 2. In an envelope-making machine having a carrier for thenewly gummed envelopes, the combination therewith of a drying blowercomprising a fan, an air box into which air is delivered by the fan,said air box having openings therein through which the air is directedfrom the box against the envelopes carried by said carrier, and said airbox being of a relatively large size adjacent its point of connectionwith said fan and of relatively reduced size further from said point ofconnection with the fan for the purpose set forth.

In an envelope-making machine having a carrier for the newly gummedenvelopes, the combination therewith of a drying blower comprising afan, an air box into which air is delivered by the "fan, said air boxhaving openings therein through which the air is directed from theboxagainst the envelopes carried by said carrier, and said air boxbeing'separately formed and detachable from said fan.

4. In an envelope-making machine having a carrier for the newly gummedenvelopes, the combination therewith of a drying blower comprising afanyanair box into which openings providing a greater area of dis chargefor the air nearest to said air receiving opening and relatively lessarea of discharge further from said air receiving opening. y

6. An air box for drying blowers comprising a box otherwise closed onall sides but having an airreceiving opening in one wall and having aplurality of air discharge openings in another wall, the air dischargeopenings providing a greater area of discharge for the air nearest tosaid air receiving opening and relatively less area of dis chargefurther from said air receiving opening, and said box being of a sizegreatest nearer said air receiving opening and being tapered to asmaller size further from said air receiving opening.

In testimony whereof I afiix my signature in the presence of twowitnesses.
